Filed: 2008-06-04
Abstract: <P>PROBLEM TO BE SOLVED: To provide a radar device capable of detecting the number of objects existing at an approximately equal relative distance mutually, without making the processing complex.  <P>SOLUTION: An image processing part 10 calculates the reception time until receiving a reflected wave obtained, by reflecting a radiated electromagnetic wave by another vehicle imaged on an image imaged by a camera 101. Furthermore, the image processing part 10 calculates a relative distance to another vehicle, counts the number of other vehicles existing at an approximately same relative distance as the calculated relative distance, and associates the counted number with the calculated reception time. A radar processing part 11 compares the reception time of the reflected waves when correlation generates a peak value with a reception time calculated by the image processing part 10, while calculating the correlation between the radiated electromagnetic waves and the reflected wave, and specifies the number of other vehicles correlated with an approximately equal reception time. The radar processing part 11 calculates the relative distance, based on the reception time of correlation generating the peak value, and correlates the predetermined number of other vehicles.  <P>COPYRIGHT: (C)2010,JPO&INPIT

Title: Switching led driver circuit

IPC: H03K17/78
Filed: 2008-07-03
Abstract: <P>PROBLEM TO BE SOLVED: To provide an LED driver circuit capable of enhancing light intensity of an LED without an increase in heat.  <P>SOLUTION: The LED driver circuit causes flickering in a high frequency by sequentially and repeatedly switching a plurality of LED arrays. A PWM (pulse width modulation) generator outputs n pieces of continuous high frequency periodic PWN signals. Although respective continuous periods (T) and duty cycles (d) of the PWN signals are the same as each other, pulse parts of the PWM signals sequentially continue with time, that is, d=1/n. Each PWM signal is transmitted to a dimming constant current source to separately output driving power at the same timing as that of an input PWM signal to one of the LED arrays, and consequently, the LED array is subjected to high frequency flickering. The flickering frequency of each of the LED arrays and the whole LED arrays are 1/T Hz and n/T Hz, respectively. They are not continuously turned on, thereby driving current of the LED increases over rating average forward current I<SB>AVG</SB>to achieve a visual effect by the survivability of vision of eyes.  <P>COPYRIGHT: (C)2010,JPO&INPIT
